3 1 Introduction Features 24-bit/96kHz audio interface Multiple 1 analog signals (L/R) can be input simultaneously and output to a computer by USB at the same time Multiple XLR mic inputs (balanced 2 ) and standard phone jack inputs (balanced 3 /unbalanced 4 ) Electric guitars and basses, for example, can be connected to the standard phone jack inputs when the MIC/LINE INST switch is set to INST (instrument input) 5 Balanced stereo line 6 and headphone 7 outputs MIDI IN and OUT connectors Direct monitoring function allows input monitoring with low latency USB port (USB-B type, USB 2.0 standard) Use the included USB cable to connect the unit to a computer. To connect to an ios device, use a Lightning to USB Camera Adapter made by Apple Inc. When using a US-2x2 that is connected to a computer, it will operate using USB bus power. However, the power supply will be insufficient when using the unit connected to an ios device by USB, so you will need to purchase a separate AC adapter designed for use with this unit (TASCAM PS-P520, DC5V). (When using a US-4x4, always connect the included AC adapter.) A driver is included for use with Windows computers, and a Settings panel application is included for use with Macs DAW software included (SONAR LE, Ableton Live Lite) SONAR LE only supports Windows computers. Ableton Live Lite supports both Windows and Mac computers 1 US-2x2: 2 inputs, US-4x4: 4 inputs 2 XLR-3-31 equivalent US-2x2: 2 inputs, US-4x4: 4 inputs The US-2x2 has XLR/TRS combo jacks 3 Standard 6.3mm (1/4") TRS stereo jack (MIC/LINE INST switch set to MIC/LINE) US-2x2: 2 inputs, US-4x4: 4 inputs 4 Standard 6.3mm (1/4") TRS stereo jack (MIC/LINE INST switch set to INST) US-2x2/US-4x4: both 2 inputs 5 Only IN1-IN2 on the US-4x4 6 Standard 6.3mm (1/4") TRS stereo jack US-2x2: 2 outputs, US-4x4: 4 outputs 7 Standard 6.3mm (1/4") stereo jack US-2x2: 1 output, US-4x4: 2 outputs Note about computer operation If you are unsure about anything related to the basic operation of a computer when it is mentioned in an explanation in this manual, please refer to the computer operation manual. To use this unit with a computer, dedicated software must be installed on the computer. For details about software installation, see Installing the dedicated software on page 6.

4 2 Names and functions of parts Front panel q US-4x4 front panel w q w US-2x2 front panel 1 SIG indicators The SIG indicators light green when signals (of at least 32 dbfs) are input through the IN1/IN2 jacks (and US-4x4 IN3/ IN4 jacks). 2 PEAK indicators The PEAK indicators light red when signals that are about to distort ( 1 dbfs or higher) are input through the IN1/IN2 jacks (and US-4x4 IN3/IN4 jacks). 3 GAIN knobs Use to adjust the input levels of the IN1/IN2 jacks (and US-4x4 IN3/IN4 jacks). Adjust these so that the PEAK indicators do not light red. 4 USB indicator This lights when the USB connection is working. 5 LINE OUT knob Use to adjust the output level of the LINE OUT jacks. 6 PHONES knob Use to adjust the output level of the PHONES jack. Before connecting headphones, minimize the volume with the PHONES knob. Failure to do so might cause sudden loud noises, which could harm your hearing or result in other trouble. 7 Phantom power switch/indicator Use this switch to provide +48V phantom power to the IN1/ IN2 jacks (and US-4x4 IN3/IN4 jacks). The indicator lights when the phantom power switch is set to +48V. Set the LINE OUT and PHONES knobs to their minimum values before changing the phantom power setting. Depending on the connected mics, sudden loud noises from monitoring equipment could occur, and this could damage the equipment or harm hearing. The phantom power switch changes the setting for both US-2x2 input channels (all four US-4x4 input channels) simultaneously. Do not connect or disconnect mics when the phantom power switch is set to +48V. Set the phantom power switch to +48V only when using a condenser microphone that requires phantom power. Turning phantom power +48V when a dynamic mic or other mic that does not require it is connected could damage this unit and connected equipment. Do not supply phantom power to an unbalanced dynamic mic. Supplying phantom power to some ribbon mics will break them. If you are unsure, do not supply phantom power to a ribbon mic. If you connect this unit to a laptop computer that is running on battery power and set the phantom power switch to +48V, the computer battery charge will be consumed more quickly. 8 IN1/IN2 (BALANCED/UNBALANCED) jacks These input jacks are XLR/TRS combo jacks on the US-2x2 and separate XLR and standard TRS jacks on the US-4x4. Use the MIC/LINE INST switches on the front of the unit to enable balanced line (MIC/LINE) input or unbalanced (INST) input for the standard TRS jacks. When directly connecting a guitar, bass or other instrument, set the MIC/LINE INST switch to INST. 9 IN3/IN4 (BALANCED) jacks These XLR analog mic input and standard line level TRS jacks are balanced input jacks. On the US-4x4, the IN1-IN4 (8, 9) inputs each have two jacks (XLR and TRS). Do not input signals through both jacks of the same input at the same time. If signals are input through both at the same time, neither signal will be received properly. 0 MIC/LINE INST switches Set according to the IN1/IN2 jack input sources. Set to MIC/LINE when connecting electronic instruments, audio devices, mics and similar equipment. Set to INST when connecting an electric guitar, electric bass or other equipment with high output impedance. q MONITOR BALANCE knob When recording input signals, use this to adjust the monitoring balance between the signals from this unit's input jacks and from the computer. The volume of signals input through this unit's input jacks increase the more the MONITOR BALANCE knob is set to the left (INPUT) and signals output from the computer increase the more this is set to the right (COMPUTER). This knob does not affect the recording level of input signals. w PHONES jack Use this standard stereo phone jack to connect stereo headphones. Use an adapter to connect headphones with a mini plug. 4 TASCAM US-2x2/US-4x4

10 4 Preparation Connecting the power US-4x4 Connect the power to the US-4x4 as shown below. * The AC adapter for the US-4x4 includes two types of outlet plugs. Attach the type of plug that matches the power outlet that you are using. Changing the outlet plug (US-4x4 only) Power outlet GPE Z (included) DC plug 1 Move the latch on the AC adapter in the direction of the arrow. 2 Pull off the outlet plug. 3 Replace it with the other outlet plug (A or B). 4 Move the latch on the AC adapter in the direction of the arrow again. 5 Attach the outlet plug to the AC adapter. This completes changing the outlet plug. After changing the outlet plug, confirm that is not loose or crooked and that everything is normal before plugging it into an outlet US-2x2 Normally, when a US-2x2 is connected to a computer, it will operate using USB bus power, so a separate power supply is not necessary. However, when using the unit connected to an ios device, a separate AC adapter designed for use with this unit (TASCAM PS-P520, DC5V) is necessary. In this case, connect the power source to the unit as shown below. Do not use the adapter if there is anything abnormal about the plug after changing it. Use when the plug is abnormal could cause fire or electric shock. Contact the retailer where you purchased the unit or a TEAC service center (on the back cover) to request repair. Power outlet TASCAM PS-P520 (sold separately) DC plug Always use the AC adapter designed for use with the unit: GPE Z for the US-4x4 or TASCAM PS-P520 for the US-2x2.

11 5 Connections Connecting other equipment This is an example of US-4x4 connections. Precautions before making connections Carefully read the operation manuals of the devices to be connected and then connect them correctly. Before making connections, turn this unit and all equipment to be connected off (standby). If possible, install all connected devices so that they are powered from the same AC power supply line. When using a power strip or similar device, be sure to use one that has high current capacity in order to minimize voltage fluctuations in the AC power supply. Vocal mic Guitar Bass Guitar Headphones Vocal mic Examples of connections to a US-4x4 (front) Powered monitor speakers with balanced connections Powered monitor speakers Drum machine Computer Examples of connections to a US-4x4 (back) Computer connections USB-B plug Use the included USB cable to connect the unit to a computer USB 2.0/3.0 port. When the USB connection is working, the USB indicator on the front of the unit lights. If you connect this unit to a computer via a USB hub, for example, audio signal dropouts, clicking noises and other interference could occur due to the influence of other USB devices connected to that hub. For this reason, we strongly recommend connecting this unit to a separate USB port. Connecting USB keyboards and mice, however, to the same bus should not be a problem. Audio connections Analog audio signals input into this device from mics, guitars, keyboards and other audio equipment can be converted into digital signals and transmitted to the computer via USB. In addition, by connecting speakers (through an amplifier if not powered) or headphones to this unit, you can monitor audio signals that are input to this unit and output from the computer. Before connecting audio equipment, set the GAIN, LINE OUT and PHONES knobs to their lowest values. Failure to do so could cause sudden loud noises from monitoring equipment, and this could damage the equipment or harm hearing. Microphones Dynamic mics Connect these to the IN1/IN2 jacks (and US-4x4 IN3/IN4 jacks) on the front of the unit Condenser mics When using condenser mics that require phantom power, connect them to the IN1/IN2 jacks (and US-4x4 IN3/IN4 jacks) on the front of the unit, and set the phantom power switch to +48V. When the phantom power switch is set to +48V, the phantom power indicator on the front of the unit lights. The phantom power switch changes the setting for both US-2x2 input channels (all four US-4x4 input channels) simultaneously. Do not turn phantom power +48V when connecting a mic that does not require phantom power. Do not connect or disconnect mics while phantom power is +48V. Doing so could cause a loud noise and might damage this unit and connected equipment. Set the LINE OUT and PHONES knobs to their minimum values before turning phantom power +48V/OFF. Depending on the connected mics, sudden loud noises from monitoring equipment could occur, and this could damage the equipment or harm hearing. Turning phantom power +48V when a dynamic mic or other mic that does not require it is connected could damage this unit and connected equipment. Supplying phantom power to some ribbon mics will break them. If you are unsure, do not supply phantom power to a ribbon mic. Guitar When connecting a guitar or bass guitar directly to this unit, use the IN1 or IN2 jack on the front of the unit and set the MIC/LINE INST switch for that jack to INST. Electronic instruments and other audio equipment When connecting an electronic instrument or other audio equipment directly to this unit, use the IN1 and IN2 jacks on the front of the unit and set their MIC/LINE INST switches to MIC/ LINE. Analog record players The output of an analog record player cannot be connected directly to this unit. To connect an analog record player to this unit, a phono amp and equalizer (or an audio amplifier that has phono input jacks) must be connected between them. TASCAM US-2x2/US-4x4 11

12 5 Connections Monitor speakers Connect monitor speakers (powered speakers or an amplifier and speaker system) to the LINE OUT 1-2 jacks on the back of the unit. Use the LINE OUT knob on the front of the unit to adjust the speaker volume. Headphones Connect headphones to the PHONES jack (standard stereo) on the front of the unit. Before connecting headphones, minimize the volume with the PHONES knob. Failure to do so might cause sudden loud noises, which could harm your hearing or result in other trouble. Connecting with ios devices US-2x2 You will need a Lightning to USB Camera Adapter 1 and an AC adapter 2 (sold separately). US-4x4 You will need a Lightning to USB Camera Adapter 1. 1 You will need to prepare an Apple genuine Lightning to USB Camera Adapter (sold separately. 2 DC5V TASCAM PS-P520 AC adapter (sold separately) MIDI connections Connect sound modules, keyboards, synthesizers, drum machines and other MIDI devices to the unit in the following manner. iiif you want to monitor sound from a MIDI device, connect its outputs to this unit's LINE IN or use in external mixer. iiyou can also use the MIDI IN and MIDI OUT connectors on the back of the unit to send and receive MIDI timecode (MTC). By doing this, you can use an application that supports MTC to synchronize a multitrack recorder (MTR) and MIDI devices. The MIDI IN and USB indicators might stay lit even after the connected computer is shut down. This is because some computers continue to provide power through USB cables even after being shut down. The MIDI IN indicator lights when the unit is receiving MIDI data through the MIDI IN connector. If you connect a device that sends MIDI active sensing messages, this indicator will blink constantly. In order to avoid this, disable MIDI active sensing on the connected device. When using Windows Media Player, if the Sound and Audio Devices Properties Control Panel MIDI music playback (default device) is set to Microsoft GS Wavetable SW Synth, you will not be able to hear MIDI performances through this unit's LINE OUT [BALANCED] or PHONES jacks. 12 TASCAM US-2x2/US-4x4

TASCAM US-2x2/US-4x4 13

14 6 Using the Settings Panel 3 Buffer Size item (Windows Only) The driver for the unit stores the audio input and output signals transferred to and from the computer temporarily in a buffer. This buffer size can be adjusted. Smaller buffer sizes result in less audio signal delay (latency), but require high-speed processing by the computer. If the processing cannot keep up, for example, due to other system operations, clicking and popping noises might occur and the audio signal might even drop out. Increasing the buffer size will stabilize operation and suppress negative effects on audio signals, but the delay in audio signals sent to the computer will increase. You can use the slider on the panel to adjust the buffer size, according to the use conditions. Use the slider to select fixed values that increase from left to right (64, 128, 56, 512, 1024 and 2048 samples). 4 Audio Input items Turn input on/off for each channel separately. iiturn an input on by putting a check in its checkbox. When an input is on, signals on that channel will be input. iiturn an input off by removing the check from its checkbox. When an input is off, signals on that channel will not be input. 5 Line Outputs items Line Output 1-2 iiselect the signals output from the unit s LINE OUT 1-2 and PHONES jacks. Line Output 3-4 (US-4x4 only) iiselect the signals output from the unit s LINE OUT 3-4 jacks.
